Fix add reference action on macros.

[mdx97]

Before we were using the range of the corresponding expression node in the macro expanded file, which is obviously incorrect as we are setting the text in the original source.

For some reason, the test I added is failing and I haven't found a way to fix it. Does anyone know why check_fix wouldn't work with macros? Getting this error:

thread 'handlers::type_mismatch::tests::test_add_reference_to_macro_call' panicked at 'no diagnostics', crates/ide-diagnostics/src/handlers/type_mismatch.rs:317:9

closes #13219

The test is failing because String is no defined (tests don't know about std). so just add a struct String; to your fixture and it should work

@Veykril thanks Lukas. I will fix that up after work today.

I just went ahead and used a u64 instead.

Thanks!
